Distribution of Elements "in a High-Carbon, Low-Phosphorus, Open-Hearth Ingot, 14 inches square, 63 inches long.
NOTE.—Made by The Pennsylvania Steel Company.   Carbon was determined by color, and Is, therefore, only approximate.

universal plate, the second slab into a three-eighth-inch sheared plate, the third slab into a half-inch universal plate, the fourth slab into a half-inch sheared plate, and the fifth slab was hammered into a bloom and rolled into 6"x4" angles.
Each end of each slab was marked so as to note whether it was toward the top or bottom of the ingot, and the location of each testTpiece in each plate was kept on record. Table XIII-0 gives the results obtained from the different strips, while the diagram immediately below the table represents the entire length of the original piece produced by rolling the 18"xSO" ingot to a section of IB'^S"* The numbers on this diagram correspond to the numbers of. the test-pieces in the table, and mark the place in the ingot from which the corresponding test-piece was derived.
